Yep. I get a vague image but sometimes struggle to flesh it out. Like my personal Nevada has a long face and high cheekbones - I think that was because of the Native American ancestry mention sinking into my brain, and doesn't look very strong on the surface, because that always comes as a shock to the other characters. But I struggled a bit to get a really clear picture.
And I find it so hard to imagine stubble, even though I like it in real life and it's the permanent state of my husband's chin. It goes all cartoonish in my imagination.
